A person who is 1.5 meters tall casts a shadow that is 8 meters long. The distance along the ground from the person (N) to the flag pole (G) is 32 meters. What's the height of the flagpole?

Answer is 6 meters. As a person with height of 1.5 meters casts a shadow of 8 meters which 5.3333 ... times greater than the real height, using this relation we can find the real height by dividing the length of shadow by 5.3333 ... So the height of pole is: 32/5.33333 = 6 meters
